Patent DE-3235980-A1 (DE)
Title: Lifting and lowering platforms, especially for theatre stages
Inventor: DIEBAN PETER-H ING GRAD
IPC: E04H3/12
Filed: 1982-09-29
Abstract: To design a stage set, it is absolutely essential to construct the stage floor according to requirements. For this purpose, according to the invention the stage surface is divided, in the manner of a chessboard, into partial sections which can be lifted and lowered vertically or separately from one another as lifting and lowering platforms 12, the platforms being connected to an upper and lower steel supporting framework 13 and 14 respectively, and the corner columns 17a, 17b of the steel supporting frameworks 13, 14 serving as guide elements. The steel supporting frameworks 13, 14 are moved by chains 3, 5d which engage on cross-struts 6a, 6b of the steel supporting frameworks 13, 14 and compensate for the dead weight of the same by means of balancing weights 7a, 7b. 
<??>For improved relief design of the stage floor, in addition to the vertical movement of the first and uppermost platform element 12a provision is also made at the corners thereof for a spindle drive which permits pivoting movements about horizontal x,y axes.

Patent DE-3344181-A1 (DE)
Title: Vane pump
Inventor: HERTELL SIEGFRIED DIPL ING
IPC: F04C2/44
Filed: 1983-12-07
Abstract: An essential characteristic of vane pumps is the attachment of the vanes on the rotor or vane block support by hinges, whose axes are equidistant from the vane block axis and are arranged in parallel to the latter. In a simple embodiment, centrifugal force causes the free ends of the vanes to bear on the internal wall of the casing. The ends of the vanes can be supported by rollers or can be formed as dynamically acting vane edges. In a further development, the free vane ends are to be positively guided. To this end, the internal faces of the end walls, for example, are provided with grooves, in which run guiding pins or guiding rollers laterally attached to the vane ends. Another embodiment comprises the arrangement of rods, which are mounted in the casing axis and which, passing through the vane block wall, are connected at their free ends with the vane ends in a jointed manner. Another form of positive guidance provides vanes which - in a cross-sectional view - have the form of two-armed levers having gudgeons between the two lever arms. One of the lever arms extends from the hinge into the interior of the vane block, where the end of the arm runs on a guiding surface. The vane pumps can be operated in different ways. Thus the vane block on its own, the casing on its own, or both casing and vane block at the same time may rotate. In the operational mode, where the casing rotates, positive guidance of the vanes is provided, and additionally in- and ... Original asbstract incomplete.

Title: Tilting-pad sliding bearing
Inventor: THEISSEN JOSEF DR ING
IPC: F16C17/03
Filed: 1984-04-19
Abstract: The invention relates to tilting-pad sliding bearings which are also subjected to vibrations during operation. These vibrations can also stem from the second-order, third-order or higher-order bending vibration of a rotor to be supported. Due to their high acceleration, these vibrations can cause implosions of cavitation-causing vapour bubbles, thereby causing local instances of fatigue of the sliding surfaces. Since the cavitation occurs due to an instantaneous lack of lubricant, provision is made to counteract this local lack of lubricant by providing corresponding lubrication channels without significantly prejudicing the load capacity of the bearing.
